Republican Sen. Cam Ward of Alabaster said he will co-sponsor the bill and believes it will help recruit new businesses to the state.

He said the fact that the state is right to work is an important factor some businesses consider in deciding where to locate. Ward said he has nothing against unions, but believes every worker should be free to make his own decision on whether to join.

Alabama voters in November approved an amendment that was opposed by unions. That amendment allows only secret ballots to be used on votes to allow unions to form in the workplace. Supporters say it will prevent union organizers from harassing employees, but opponents say it is aimed at stopping unions from organizing.

Dial said being a "right-to-work" state has helped Alabama officials recruit major automobile manufacturing plants.
